A woman was shot and killed Tuesday night after getting in an argument with a man in the parking lot of a shopping center in Point Loma Heights, and police are looking for her assailant.

Witnesses told police the two had been inside a Domino’s Pizza store in the strip mall on West Point Loma Boulevard near Groton Street shortly before 11:45 p.m. when they walked out to a parking lot and were heard yelling. Then a single gunshot rang out.

A dark sedan was seen speeding away, heading east on West Point Loma Boulevard. The victim, who police said appeared to be in her 30s, was found lying on the ground.

The woman suffered a gunshot wound to the upper body, said San Diego police homicide Lt. Anthony Dupree. Paramedics transported her to a hospital but doctors were unable to revive her.

Dupree said the woman was not carrying any identification and has not yet been identified. The relationship between the victim and the assailant also is not known, he said.

Police were hoping surveillance cameras in the shopping center caught the deadly confrontation.

“We're hoping (Domino's Pizza does) have cameras. We're waiting for a manager to come who has access to it. Hopefully, give us some additional information we can put out,” Dupree told NBC 7 San Diego.

Anyone with information about the shooting was asked to call homicide detectives at (619) 531-2293 or the Crime Stoppers tip line at (888) 580-8477.
